Hello, I don't speak German. I recently canceled my MagentaZuhause L connection and received a cancellation letter from Telekom, which includes instructions for returning the devices. However, I have already paid for everything when I initially got this connection and do not have any devices to return. Could you please clarify why I received these instructions? Tried calling customer service but get some auto-generated German message with it. How to contact Telekom customer support in English?
